What Threats are Posed by Cyber Security Vulnerabilities?

The cyber security landscape is constantly evolving, with new vulnerabilities and threats appearing every day. As businesses become increasingly reliant on technology, the risks posed by cyber security vulnerabilities are also increasing.
Common Cyber Security Threats
There are many different types of cyber security threats, including viruses, worms, Trojans, spyware, adware, phishing attacks, Denial of Service (DoS) attacks, and SQL injection attacks. Each of these cyber security threats can pose serious impact to businesses, both in terms of financial loss and damage to reputation.
Viruses are one of the most common types of cyber security threats. They are usually spread through email attachments or by downloading infected files from the internet. Once a virus has been installed on a computer, it can replicate itself and spread to other computers on the network. Viruses can cause a range of problems, from slowing down a computer to deleting important files.
Worms are similar to viruses in that they can spread themselves across networks. However, worms do not need to attach themselves to files to be transmitted. Instead, they exploit vulnerabilities in network systems to gain access to computers. Once inside a system, worms can replicate themselves and cause significant damage.
Trojans are another type of malware that can be used to gain access to a computer system. Trojans are usually disguised as legitimate files or programs, which tricks users into downloading and installing them. Once installed, Trojans can give attackers access to the system and allow them to perform malicious actions.
Spyware is software that is installed on a computer without the user’s knowledge or consent. Spyware collects information about the user’s internet habits and activities without their knowledge or permission. This information is then sent back to the spyware developers, who can use it for marketing purposes or even sell it to third parties. Spyware can also be used to track a user’s activities and location.
Adware is software that displays advertising on a computer system. Adware is often bundled with free programs or downloads from the internet. While some adware is relatively harmless, other forms of adware can be used to collect personal information about the user or redirect them to malicious websites.
Phishing attacks are attempts by attackers to trick users into giving away personal information such as passwords or credit card details by masquerading as a trustworthy website or email. Phishing attacks usually use emails or websites that look similar to legitimate ones to fool users into entering their personal information.
Denial of Service (DoS) attacks are designed to make a computer or network resource unavailable to legitimate users by flooding it with requests or data until it becomes overloaded and crashes. DoS attacks can be very damaging as they can prevent employees from being able to work and customers from being able to access important services.
SQL Injection Attacks
SQL injection attacks occur when an attacker inserts malicious code into an SQL database to exploit vulnerabilities in the system’s configuration or code. This attack can allow attackers to access sensitive information stored in the database, such as customer records or financial data. SQL injection attacks can also be used to delete data from the database or even take control of the entire system.
Denial of Service (DoS)
Denial of Service (DoS) attacks are designed to make a computer or network resource unavailable to legitimate users by flooding it with requests or data until it becomes overloaded and crashes. DoS attacks can be very damaging as they can prevent employees from being able to work and customers from being able to access essential services.
Man-in-the-middle (MitM) Attacks
Man-in-the-middle (MitM) attacks occur when an attacker intercepts communications between two parties in order to eavesdrop on the conversation or even manipulate the data being exchanged. MitM attacks can be very difficult to detect as they do not usually leave any traces on the systems that have been compromised.
